Loren said that some Mercedes diesels have a butterfly valve (news to me)
so if we find out why --- it may give the answer. Loren what operated your
Mercedes butterfly ?   I remember your dads Mercedes for its infected fuel
tank.


  The throttle linkage goes a mount on the engine, through the butterfly 
and then to the pump as I recall.  After 25 years, each pivot and ball/socket 

wears.  Add all those up between the throttle and the pump and I bet the 
fueling is a bit out of whack.  Dad tried running it, bypassing the butterfly 

once and said it didn't run well at all.  ('70 220D, possibly for sale this 
year.)
  The contaminated tank was on the '83TD.  No butterfly on that one.  
Will sell that one as soon as he gets a leak, loping and a little suspension 
stuff fixed.
